SPECIFICATION forming part of Letters Patent No. 284,793, dated September 11, 1883.

Application filed August 14,1282. (No model.)

T0 at whom it may concern Be it known that I, ORSON M. ALLABEN, a citizen of the United States, residing at Margarettville, in the county of Delaware and. State of New York, have invented certain new and useful Improvements in Saws, of which the following is a specification, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention has relation to saws, and more particularly to that class of saws which are provided with a planer blade or iron, whereby the lumber is sawed into boards and the sides thereof planed or dressed at one operation;

and to that end the novelty consists in the construction of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.

Figure l is a plan view of a segment of a circular saw, with a front View of the planeiron in position. Fig. 2 is a reverse view of the same. "Fig. 3 is avertical section, and Fig 4. a longitudinal section of the same.

A is the saw, and B a rectangular recess, set obliquely with reference to the diameter of the saw. The ends a a of this recess are semicircular in form, and the top and bottom are square, as shown.

O is the plane bit or iron, and its ends are provided with grooves c c to lit the ends a a of the recess B.

D is the cutting-edge of the iron, and is beveled so as to set out a sufficient distance from tate the bowing of the same when inserting or removing it from the recess B.

F is a taper-pin, passing through one-of the grooved ends 011 of the iron and saw to hold the iron rigidly in place. To insert the iron in the saw, one of the grooved ends 0 is adjusted to the end a of the recess, and the iron then longitudinally bowed or bent, so as to insert the other end, so that the spring of the iron will carry it into place. The pin F is then inserted and the iron rigidly locked in place.

. Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is

The saw A, provided with recess 13 a a, in combination with the plane-iron 0, having recessed ends 0 0, slots 6 6, holes 6 e, and taperpiu F, as set forth.

ORSON M. ALLABEN.
